Project Zomboid- not sure where to put this Thread

A long while back a friend had purchased a copy of Project Zomboid for me via the google payments option. When I had logged into my new game I saw a desura code thing and at the time I didn't know what Desura was and the friend had a rather low opinion of Desura for some reason or other.

Anyhow, I've had a Desura account for a while now and rather enjoy the games I have on it, and I'd like to have the Desura client list Project Zomboid as one of my games. I had hoped Desura would detect the game, or if I ran it, it would then be caught by Desura and added to my library list, that is unfortunately not the case apparently.

To get PZ onto my Desura, would I have to re-purchase the game?

Apologies if this is in the wrong area and if there is another topic that addresses this- I haven't found said topic and I am unsure as to where to put this.

Hey there head here and fill out the form to get the game on your Desura account Indiedb.com
